The measurements outside North America are reciprocal, e.g. 7.7L/100km (which is awfully inefficient for a diesel, normally it should be around 5L)
So converting gallon to liter, and mile to kilometer is the wrong way to present it.
As for the efficiency in general - of course electric engines have a very high efficiency (in the 90s), unlikely diesel which can barely hit 35%.
